【问题描述】：

如何在C#代码中获取系统的CPU、RAM和磁盘驱动器使用情况？

【参考方案1】：

驱动器

static void Main(string[] args)

var drives = DriveInfo.GetDrives();
foreach (DriveInfo info in drives)

      Console.WriteLine("Name: 0\nSize: 1\nDrive Format: 2", info.Name, info.TotalSize, info.DriveFormat);

 Console.ReadLine();

【参考方案2】：

这是一个输出磁盘使用情况的解决方案，即在轮询 Timer99 时使用的总磁盘百分比：

 using System;
 using System.Diagnostics;
 using System.Windows;

 namespace diskpercent
 
     public partial class MainWindow : Window
     
         DispatcherTimer Timer99 = new DispatcherTimer();
         public MainWindow()
         
             InitializeComponent();
             Timer99.Tick += Timer99_Tick; // don't freeze the ui
             Timer99.Interval = new TimeSpan(0, 0, 0, 0, 1024);
             Timer99.IsEnabled = true;
         
         public PerformanceCounter myCounter =
            new PerformanceCounter("PhysicalDisk", "% Disk Time", "_Total");
         public Int32 j = 0;
         public void Timer99_Tick(System.Object sender, System.EventArgs e)

         
                 //Console.Clear();
             j = Convert.ToInt32(myCounter.NextValue());      
                 //Console.WriteLine(j);
             textblock1.Text = j.ToString();
         
     
 

这里是常用性能计数器的列表：

 PerformanceCounter("Processor", "% Processor Time", "_Total");
 PerformanceCounter("Processor", "% Privileged Time", "_Total");
 PerformanceCounter("Processor", "% Interrupt Time", "_Total");
 PerformanceCounter("Processor", "% DPC Time", "_Total");
 PerformanceCounter("Memory", "Available MBytes", null);
 PerformanceCounter("Memory", "Committed Bytes", null);
 PerformanceCounter("Memory", "Commit Limit", null);
 PerformanceCounter("Memory", "% Committed Bytes In Use", null);
 PerformanceCounter("Memory", "Pool Paged Bytes", null);
 PerformanceCounter("Memory", "Pool Nonpaged Bytes", null);
 PerformanceCounter("Memory", "Cache Bytes", null);
 PerformanceCounter("Paging File", "% Usage", "_Total");
 PerformanceCounter("PhysicalDisk", "Avg. Disk Queue Length", "_Total");
 PerformanceCounter("PhysicalDisk", "Disk Read Bytes/sec", "_Total");
 PerformanceCounter("PhysicalDisk", "Disk Write Bytes/sec", "_Total");
 PerformanceCounter("PhysicalDisk", "Avg. Disk sec/Read", "_Total");
 PerformanceCounter("PhysicalDisk", "Avg. Disk sec/Write", "_Total");
 PerformanceCounter("PhysicalDisk", "% Disk Time", "_Total");
 PerformanceCounter("Process", "Handle Count", "_Total");
 PerformanceCounter("Process", "Thread Count", "_Total");
 PerformanceCounter("System", "Context Switches/sec", null);
 PerformanceCounter("System", "System Calls/sec", null);
 PerformanceCounter("System", "Processor Queue Length", null);

【讨论】：

这个给出了磁盘上的可用空间：PerformanceCounter("LogicalDisk", "FreeMegabytes", "C:")

【参考方案3】：

请搜索 SO；有几个类似的问题：

通过性能计数器类。通过更改类别。
